Corrugated plants are currently being asked to do more with less. Run lengths are shrinking, SKU counts are growing, and the pool of experienced operators is getting smaller. The pressure to stay efficient is real, and it shows up every single shift.
However, for many facilities, the answer does not require a full line replacement. Targeted upgrades to glue stations, adhesive supply systems, and operator controls can reduce changeover time, eliminate preventable downtime, and give plant managers better visibility into what is happening on their line. The payback on these kinds of improvements tend to be relatively fast and rather noticeable.
Below we discuss some of the places that these types of inefficiencies show up in facilities and what modern equipment can do to help solve them.
A More Efficient Gluing Station
Glue station setup is one of the most consistent sources of changeover delay in corrugated manufacturing. Adjusting for different flute sizes traditionally means reaching into the machine and dialing in the gap manually. The process is time-consuming, varies between operators, and becomes increasingly costly as plants run more SKUs in shorter runs.
Solutions like Valco Melton's BoardRunner Gluing Station with AutoGap Adjustment eliminates that process entirely. Operators can select from four pre-set flute sizes using an external interface, eliminating wrenches, reaching into the machine, and the inconsistent adjustments between operators. Air pressure automatically adjust to match the board size, ensuring proper contact across all box styles. Once the flute size is calibrated, consistent and repeatable setups become the standard, not the exception.
For plants managing multiple job types across shifts, the time savings are immediate. More importantly, the quality consistency that comes from automated gap control reduces adhesive waste from improper contact pressure and protects finished box integrity at the end of the line.
Taking Control of Adhesive at the Source
Adhesive can be an overlooked cost center in a corrugated plant. Without real-time monitoring, consumption data is largely invisible, pressure fluctuations can go undetected until a quality issue surfaces or adhesive supply issues create unplanned downtime. Manual checks introduce variability that grows more problematic as operations scale.
Systems like the DD-1 Intelligent Pump change the economics of adhesive management. Combining proven electronic reversing control with intelligent monitoring capabilities, the DD-1's solid-state electronics operate reliably at pressures as low as 4 PSI without the "hang-up" and stalling issues of conventional mechanical pumps. More importantly, it brings real-time visibility to a process that most plants have been running blind. Operators can track glue consumption, reset totals with a button press, and measure the actual adhesive savings when switching between bead and dot application. Proactive alerts for low glue levels and pressure fluctuations give your team the information they need before a problem becomes a production stoppage.
For facilities ready to take adhesive management to the next level, the DD-1 serves as the foundation for Valco Melton's Intelligent Central Pumping Stations, a fully automated solution designed specifically for multi-line corrugated operations.
Centralized Adhesive Supply Without the Guesswork
For corrugated facilities with multiple lines, adhesive supply disruptions are a preventable source of downtime. When a tote runs dry and air enters the lines, production stops. The impact is not limited to the line itself; it creates waste that affects the entire operation.
The Intelligent Central Pumping Station transforms traditional adhesive supply into a fully automated, continuously monitored operation. Built on the DD-1 platform with advanced controls, the system automatically switches between totes before one runs dry, preventing air from entering the lines and keeping production running without operator intervention. The touchscreen HMI gives real-time visibility into tank levels, glue and air pressure, pump status, and solenoid activity across the entire station.
What makes this system particularly valuable for plant management is the data it captures over time. Historical trend graphs, replenishment records, volume consumption logs, and tank switchover records provide the visibility needed to optimize inventory planning and hold the operation accountable. Key capabilities include:
• Automatic tote switching with zero production interruption
• Real-time tank level and system pressure monitoring
• Configurable warning and alarm thresholds
• Historical consumption logs for inventory planning and staff accountability
• Pump stroke counting and volume tracking for consumption accuracy
Streamlined Setup and Quality Control
Managing glue station configuration and quality assurance from separate interfaces adds unnecessary complexity to the operator's job. Navigating multiple systems during a job change costs time and increases the potential for setup errors, particularly as facilities bring on operators with less tenure on specific equipment.
OneView is Valco Melton's answer to that challenge. Designed as a central display for flexo-folder-gluers, the intuitive touchscreen interface consolidates glue station control and quality assurance into a single, easy-to-navigate system. It supports up to 48 valves and stores up to 1,000 jobs, making it equally suited for high-mix operations and high-volume runs. Available in 10" and 22" formats, OneView connects to MCP-4J, MCP-8, and MCP-8i controls, and is compatible with both contact and non-contact applications.
What sets a system like OneView apart for quality management is its sensor screen capability. As products pass through the line, OneView displays a graphic representation of the product in real time, showing exactly what the sensor is detecting. Glue patterns, flap length, barcode inspection, and more are visualized on screen in a format that operators can actually read and act on. Quality reports are generated automatically for every job. When something is off, operators see it immediately rather than discovering it at the end of the run.
Modernization Does Not Have to Mean Starting Over
For corrugated plants to gain ground today it doesn’t necessarily require replacing your line with and entirely new one. It can mean taking what you already have and making it smarter. Automated glue station setups reduce changeover time and operator error. Intelligent pumping systems eliminate a whole category of unplanned downtime and give management actual data on adhesive consumption. A unified operator interface simplifies set-up for operators, making consistent quality less dependent on individual experience.
These targeted upgrades help restore machine uptime without requiring full line or system replacement. For facilities running diverse product mixes while protecting margins, managing rising costs, and operating with a less experienced workforce, practical efficiency improvements have become essential.
